I started a fan page a while back and it's actually been a very easy way for people who spend a lot of time on Facebook to follow my blog rather than subscriving via traditional RSS feeds.
Initially I had it set up with a truncated blog post to auto-upload after I posted on my blog (this way readers still needed to click through to the blog to read the entire post).
But now that the networked blogs application is available, it makes it even easier to have new posts automatically load to FB!
